What is SUSE Linux Enterprise Server for z Systems and LinuxONE?

SUSE Linux Enterprise Server for z Systems and LinuxONE is a commercial Linux operating system specifically tailored for the mainframe. This means that various z/VM operating system and z Systems hardware features are exploited by SUSE Linux Enterprise Server to ensure that resource sharing, disaster recovery, and other capabilities are available for SUSE Linux Enterprise Server for z Systems and LinuxONE.

SUSE Linux Enterprise Server for z Systems and LinuxONE lets you consolidate existing distributed workloads and bring new workloads onto z Systems servers to help minimize costs, reduce downtime, decrease data center complexity, and increase business agility.

What workloads are best suited for SUSE Linux Enterprise Server for z Systems and LinuxONE?

  • A mixture of high I/O transaction-oriented workloads and moderately CPU intensive workloads are best for mainframes.
  • Oracle, SAP, IBM middleware, and many other ISVs contribute to the more than 3,150 applications running on Linux on the mainframe.
  • Almost all of IBM's middleware applications run on SUSE Linux Enterprise Server for z Systems and LinuxONE.
  • Hundreds of open source applications that run on SUSE Linux Enterprise Server for x86 servers, such as Apache, MySQL, and Samba, also run on the mainframe.

Is SUSE Linux Enterprise Server for z Systems and LinuxONE the right hardware platform for me?

SUSE Linux Enterprise Server for z Systems and LinuxONE is the ideal choice for:

  • Mainframe customers with existing mainframes that want to add Linux and benefit from the combined advantages
  • New customers that decide for the first time to buy a z Systems machine running Linux

This combined solution is ideal for customers that:

  • Host hundreds of virtual servers that run a mix of workload types and need to consolidate their environment
  • Are experiencing or projecting IT growth and want a better way to manage that growth with z/VM
  • Struggle to host I/O and data-intensive workloads in virtual servers with acceptable levels of performance, scalability, availability, capacity planning, or disaster recovery
  • Need high I/O bandwidth and scalability, or rock-solid system security

In what ways can Linux be run on the mainframe?

On an IFL, Linux can run in standalone mode in a logical partition (LPAR) and under z/VM. Currently, approximately 95% of Linux deployments on z Systems are run under z/VM.
